Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

Consider the task set in Table 1. a) Assume one of the tasks in Table 1 has its deadline reduced by 1. Now, what is the most efficient schedulability test for determining whether the task set in Table 1 is schedulable under preemptive RM?
Feature Scaling is a technique to standardize the independent features present in the data in a fixed range. It is performed during the data pre-processing to handle highly varying magnitudes or values or units.In this approach, the data is scaled to a fixed range - usually 0 to 1. A min-max scaling is typically done via the following equation: X scaled = x Xmar Eg. Given a sequence [ 1, 2, 3, 4, 5] The min-max scaled version would be [0, 0.25, 0.50, 0.75. 1.0 ] # Perform min-max scaling scaling on all the columns of 'df_new' # Store the modified dataframe in a new dataframe 'df scaled' #YOUR CODE HERE: Python # Generate descriptive statistics after min-max scaling # Observe that the min and max statistics have been modified df scaled.describe() Python
